Improvements of the FFT plugin

(1/1)

nofish:
I was very excited when the FFT plugin was implemented in Rockbox.
Since I record a lot with my iriver h120 I thought it could be a cool recording helper (eg finding a good recording position for loud sources, concerts etc. where headphones are not of much use).

But afaik until now it only works for played back files, not on the inputs.
So I asked the dev if it would be possible to also have it working on input and he said it could be done relatively easy but he doesn't have the time to do it.

Unfortunately I don't have a clue about coding and stuff...
Would anyone be up for doing this ?

Other ideas for the FFT plugin:

- adjustable slope
- cumultative (average) display over time
- all sorts of fancy stuff, something like this:  :D

dreamlayers:
I was wondering if the FFT plugin could get a display mode like Synaesthesia. It uses FFT and stereo to display a 2D image with the horizontal axis being stereo position and the vertical axis being frequency. Images from older sounds fade as new sounds are drawn. It's simple but impressive, and it truly deserves the name Synaesthesia.

I thought about porting the core of Synaesthesia, but it uses floating point math, so then I thought the integer FFT routines in the plugin could be used instead. I wish I understood FFT well enough to understand how Synaesthesia uses the data. I guess it shouldn't be hard to at least do a monochrome version.

Having another look at the patches, I found that there's already one that makes the FFT plugin working on input.

Nice !

Could anyone tell me what's the status of this patch, will it be integrated in the official release ?

Chronon:
It looks like it hasn't been touched since April of last year.  It's always possible that someone will get into shape and get it included in SVN.  After that it would be part of the next major release or available immediately in "current builds".  However, if nobody works on it then it won't get included.
